Application filed August 25, 1911. Serial No. 645,964.

T 0 all whom it may concern Be it known that I, An'rnun E. ANAKIN, a citizen of the United States, and resident of Salt Lake City, in the county of: Salt Lake and State of Utah, have invented a new and useful Auxiliary Locking Device. for Safe and Vault Doors, of which the following is a specification.

This invention relates to improvements in auxiliary locking devices for application to safe and vault doors, the primary object'being to provide a simple locking mechanism cooperating with the main locking mechanism in such a manner that the former will be automatically thrown into action when the main mechanism is subjected to abnormal pressure, or tampered with to gain unauthorized entrance thereto.

A further object of my invention is to ])10"i(le such a device as hereinbefore premised which is readily adaptable to application to the doors of new or old safes, or the like. i

lVit'h the above and other objects-in view, this invention consists of the construction, combination and arrangements of parts, all. as hereinafter more fully described claimed and illus rated in the accompanying drawings, wheroin":

Figure 1 is a front ele'ation of a safe partly broken awayto show the auxiliary locking device in inactive position: Fig. 2 is an interior view of the front portion of a safe showing the locking device in operated position: Fig. 3 is a side elevation of the locking device cooperating with the permutation lock of the safe; Fig. 4 is a similar view to Fig. 3 showing the locking lever connected to the spindle of the lock aforesaid; Fig. 5 is a view of the locking bolt used in my invention; Fig. 6 is a side elevation of the locking levcralone; Fig. 7 is a front elevation of the. same: and Fig. 8 is a view showing a modified form of locking lever for use in connection with certain forms of locks. Fig. 9 is a detail view broken away, and showing more clearly the frangible cover applied to the recess in the safe.

Throughout the following detail description and on the several figures of the drawings; similar parts are referred to by like reference characters.

Referringnow to the drawings, my invention comprises a tubular supporting member 12, one end of which is threaded, as

indicated at 7, and adapted to be screwed into the side of a safe or vault door. Movabl-y mounted on the supporting member 12 is a depending arm which may be suitably adjusted on the member 12 by means of a set screw 2, passing through the upper portion 2 of said arm. The lower portion of the arm 5 is provided with a plurality of openings 15, through one of which is inserted a bolt 14, said bolt also passing through the opening 17, in and forming a pivot for, the lever or looking member 3. At a suitable point on the upper portion of the lookingmember 3 is formed av laterally projecting lug 5, while at its lower portion the said lever is bent laterally to form the projection 4.-. The said projection 4 is adapted to lightly bear against the spindle of the conventional form of permutation lock A, operating the main bolt work.

Slidably mounted in the tubular supporting member 12 is provided a locking bolt 9 having a recess 6 formed near one end into which projects a screw 13 passing through the supporting member 12 aforesaid, said recess being designed to limit the outward movement of the bolt, as will hereinafter appear. At the inner end of the member 12 is housed a coiled spring 19 adapted to bear against the end of the looking bolt 9, said bolt. being normally held in retracted position by means of the lug 5 passing through a slot 11 in the supporting member 12 and into a diagonal slot 16 in the bolt 9. The tubular member 12 may be-suitably closed at one end by a plug 10, or other stop member used, against which the spring 19 is adapted to bear opposite the bolt engagingend.

Formedin the jainb of the safe is a recess 8 opposite the supporting member 12 and into which the locking bolt 9 isadapted to be received when thrown into active oper-' ated position. For reasons apparent to those skilled in the art to which this device pertains, I prefer to conceal the recess 8 with a frangible cover 8 preferably of a similar color to the safe, the object of which is to prevent the location of the auxiliary locking bolt when the safe is in open position. The locking lever 8 has also provided near its upper extremity an opening 20 through which may be passed a fine wire, said wire also passing around the supporting member 12 to provide an auxiliary means for securely holding the lug 5' in I engagement with the bolt 9 by the auxiliary device comprising my invention. Sudden jars, such as might be caused by the closing of the door or otherwise will thus be prevented from operating the auxiliary locking device.

Having in view the adaptability of my device to both new and old safes, it. maybe desirable to provide adjustable means in order that the locking member 3 may efl'ectiially cooperate with the main locking mechanism or combination lock. This adjustable connection may be readily effected by means of raising or lowering the look ing member 3, and passing the bolt 14 through any of the openings 15 as desirable.

Theslot 16 is preferably slanted in the opposite direction from that in which thebolt 9 is pressed by the coiled spring 19, and

it will be evident that any jar exerted thereon or the ordinary pressure of said spring, will tend to more firmly wedge the lug 5 into said slot.

From the foregoing description, the operation of my device will be readily understood. The locking member 3 is adapted to bear against the spindle of the permutation lock A, as shown in Fig. 4 of the drawings, so that if said lock be forced inwardly, or tan'ipered with, the member 3 will swing backwardly atits lower portion and out wardly at the upper part thereof, disengaging the h1g5 from the slot 16 in the locking bolt- 9. The spring 19 will then force the looking bolt through the frangible covering and into the recess 8 in the jamb of the safe, The main locking mechanism may be forced entirely into the safe and the usual bolt work'withdrawiufl but the door will be efiectually held in closed position by the auxiliary device above described. Said device may be withdrawn only by boring into the door of the safe at the proper location, and the unauthorized opening of said door is thus protected. 7

ln Fig. 8, I have shown a modified form or loekin member 3 which may be used as require by the diil'erent forms of permutation locks. It will also be apparent that the mechanism hereinbcfore. set forth may be applied tothe door so "as to permit the auzi iliary looking bol tor bolts to work either til.)

the same retracted and inactive, the other s end of the locking member engaging the spindle so as to be operated by abnormal movement of the latter.

2. In combination, a safe or vault comprising a d0or,'main locking mechanism therefor, auxiliary locking means comprising a. tubular supporting member, a bolt mounted therein, a spring to project the said bolt, an arm supported by said support ing member, a locking memberengaging the bolt to hold the same inactive and adjustable on the arm and operable by abnormal move:

ment of the main locking mechanism k 3. An. auxiliary locking means for safes comprising a tubular supporting member, a

spring actuated bolt mounted't-herein, an

arm movably mounted on said tubular sup porting member, a lever adjustably pivoted to said arm, the tubular member having a slot and the bolt having a notch corresponding to said slot and normally engaged by the locking lever to hold the bolt retracted,

a door supportin the locking lever, and main locking mec anism on the door comrisin a s indle arran ed to en we the l i .5 P g g s locking lever to actuate the same and release the bolt on abnormal movmentof the main'locliin mechanism 4. ln com ination, a safe or vault, a door therefor, main locking mechanism for the defer, auxiliary locking means on the door, a Wall olthelsafe having a recess to coiiperate with the auxiliary mechanism, and a frangible cover for said recess ARTHUR E.
